## Background
I. BACKGROUND OF THE INVENTION
The present invention relates to butter applicators and more particularly pertains to a new butter heating and dispensing system for facilitating distribution of melted butter.
II. DESCRIPTION OF THE PRIOR ART
The use of butter applicators is known in the prior art. Illustrative examples include: U.S. Pat. No. 4,477,023; U.S. Pat. No. 5,065,927; U.S. Pat. No. 5,611,206; and U.S. Pat. No. 5,955,114.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a system which allows a user to control a quantity of butter dispersed as well as the area in which the butter is dispersed with a one handed operation.
III. SUMMARY OF THE INVENTION
Perhaps one of the most popular uses for butter is to pour its sweet creamy goodness over a towering mound of fluffy popcorn. As many popcorn lovers would attest, butter is the essential ingredient that brings out the best flavor of this versatile and nutritious snack. While pre-buttered, microwaveable popcorn is widely used, more health-conscious consumers choose to air-pop their own corn. To accent it, these snackers also prefer to melt pure, real butter in a saucepan. While this method of popcorn preparation is more healthy and results in a better tasting treat, heating the butter in such a manner can present challenges. Particularly, it is difficult, if not impossible, to evenly distribute melted butter from a saucepan so that it sufficiently coats every kernel of corn. Instead of clinging to the popcorn, most of the hot liquid tends to run down and settle into the bottom of the bowl. In addition, stovetop butter melting can be a messy endeavor, as errant pouring can result in a greasy range and grimy countertops. Moreover, pouring hot melted butter from a saucepan puts the user at risk for painful burns, as the liquid could easily splatter onto the hands and arms.
The present invention provides a more efficient means of adorning popcorn, as well as any other food item, with melted butter. Simply stated, the present invention is a spray container with heating element that is specially designed to facilitate the application of hot liquid butter to foods. Featuring the shape and design of a small coffee cup, the container would be fabricated of a durable plastic or ceramic material and measure approximately three and three quarters inches (33⁄4′′) in height, two and three quarters inches (23⁄4′′) depth, and nine point forty-two inches (9.42′′) in total circumference. The interior of the container assembly or “cup” would feature a thin coating of thermal lining that would serve to keep its heated contents warm. In addition, the bottom interior of the cup would be sloped at an angle of approximately twenty degrees (20°) to ensure that all liquid would be dispensed from the container. Serving as the top of the cup, the specially configured pumping apparatus would be generally circular in shape and feature a recessed, threaded bottom lip to snugly fit into the cup when applied. For additional security, two swivel mounted wire clips could be positioned on the outer rim of the lid to lock it into place. Other components of the pump would include a thumb operated plunger that is integrally connected to a small, elongated hollow tube extending from the bottom of the lid. In operation, the invention would distribute melted butter through a circular, perforated nozzle measuring approximately one half inch (1⁄2′′) in diameter. The nozzle and pump apparatus are designed to emit a spray that is three inches (3′′) in diameter and that would reach a minimum of seven inches (7′′) from the nozzle. The heating assembly would also be comprised of a plastic or ceramic material and rendered in the shape of an “L”. The bottom interior of this component would contain the necessary electrical heating source for the externally positioned warming surface. Featured on the upright portion of the “L”, three heat transfer points would be connected to a small, red, light emitting diode (LED), visibly positioned on the side panel of the heating element. When the cup is warming, the transfer points connect to the cup's thermal lining, activating the LED when the liquid has finished heating. Electrically powered, the invention's heating assembly would feature a corded plug that could be inserted into any AC outlet.
Use of the invention would be very simple and straightforward. First, the user would fill the cup with butter, whether it is a portion of a stick or scooped from a whipped variety. Placing the lid on the container so that the hollow tube is positioned at the lowest point of the cup, the user could fold down the wire locks to secure the lid in place. After plugging in the heating element, the cup would be placed onto the heater's surface, where the buttery contents will warm and melt until the LED indicates that the cool solid has been converted into a heated liquid. Gripping the cup by the handle, the user would then depress the thumb operated plunger to spray the delectable butter over every single kernel of popped corn. Similarly, the invention can be used to completely adorn other food items such as baked potatoes, warm biscuits, corn on the cob, or any other desired entrée. In addition, the user could spray butter from the invention onto baking pans and skillets. After used, the cup itself could be easily cleaned in a dishwasher or with soap and water, and the heating assembly safely wiped down with a damp cloth.
There are several significant benefits and advantages associated with this unique product invention. Foremost, the invention would provide butter connoisseurs with an easy, safe, and mess-free means of evenly distributing their favorite condiment over virtually any food item. Featuring a cleverly designed spraying mechanism, this practical product would easily coat meats, breads, potatoes, and popcorn with the sweet and delicious taste of butter. Eliminating the need to heat butter in a saucepan, the invention could render a solid butter stick into a warm, savory liquid in a matter of minutes. In this manner, users can avoid the messy cleanups commonly associated with saucepan butter melting while also eliminating the risk of painful burns. While the invention was primarily conceived with butter in mind, other accenting oils, such as the popular and delectable olive oil, could be conveniently heated and sprayed with this product.
To this end, the present invention generally comprises a container assembly, a spray assembly, and a heating assembly. The container assembly includes an interior space for receiving a quantity of butter to be melted and dispensed. The spray assembly is operationally coupleable to the container assembly. The spray assembly includes an intake for liquid butter, and a spray nozzle for dispersing the liquid butter. The heating assembly is for providing thermal energy to melt the butter received by the container assembly. The heating assembly is thermally coupleable with the container assembly. Most preferably, the container assembly has a sloped bottom wall, which slopes downwardly towards the intake of the spray assembly.
